Peace Beneath the City sketches

For the Song Title prompt at Illustration Squared, I'm working on a drawing called "Peace Beneath the City". Here are my basic sketches:

Here's the basic thumbnail for my piece. The composition is a bit different from what I normally would do, but I quite like tall, skinny images. I think it will be interesting to try my hand at one. It seemed to fit what I wanted to do.

A bit of a close-up sketch of what's going on in the bottom of the picture. It obviously needs some tweaking, but it's a start.

Stay tuned for the finished piece!
